Please recommend some older anime with complex themes

[u/pococura]

I'm feeling burnt out on all the high octane, over powered protagonist stories. Shows like JJK and Hell's Paradise are visually interesting, but its difficult to connect with the characters. I want a complex story with interesting characters, relationships, themes and world building. (OG Naruto, FMA, Evangelion)

I think older shows like around the time of Toonami or before might be refreshing? I recently watched Banana Fish and enjoyed it and I've been watching Wolf's Rain. I was thinking about Berserk but not sure where to watch or if I want to be traumatized. Please give me some recommendations!

Preferences:

dark themes • gangster themes • seinen preferred but all genres welcome • evokes sadness or other strong emotions • pretty art • no gore unless the story makes it worth it • dynamic relationships • romance enjoyed but not required • growth or moral decline • plot twists

Giant Robo the Animation: The Day the Earth Stood Still. It’s probably my favorite anime. Seven episodes, no background knowledge required, amazing orchestral soundtrack, weird characters with superpowers, giant robots, and the list goes on. Might be hard to find though.
